Abstract
Trace iron(II) is determined spectrophotometrically after adsorption of its ternary complex with 3-(4-phenyl-2-pyridyl)-5,6-diphenyl-1,2,4-triazine and tetraphenylborate on microcrystalline naphthalene at pH 5.1-7.4. The absorption maximum is at 567 nm; the molar absorptivity is 2.9 x 10(4)lmole(-1)cm(-1).
摘要
在pH值为5.1 - 7.4的条件下，痕量亚铁离子与3-(4-苯基-2-吡啶基)-5,6-二苯基-1,2,4-三嗪和四苯基硼酸盐形成的三元配合物吸附在微晶萘上后，用分光光度法测定痕量亚铁离子。最大吸收波长为567 nm；摩尔吸光系数为2.9×10⁴L·mol⁻¹·cm⁻¹。
